Hi,
My X-10 setup is going quite well (mostly thanks to the help & advice from this forum), but I am having one problem. We want to be able to control the outside lights with our keychain remotes (or any RF remote for that matter). The lights in front work fine, but the lights in back are on a circuit run from the garage, which is on a subpanel from our main. I originally thought a phase coupler would do the trick and also considered buying a coupler / signal amplifier, but don't know if this will solve the subpanel problem. Would the coupler/repeater work out to the subpanel? Would it be bad to just put another transceiver (TM751 or RR501) out in the garage to pickup the subpanel? I know I don't want two transceivers to be sending duplicate signals, but is it different w/ a subpanel? Thanks in advance!

Does the subpanel have two 110V leads coming into it. If so I would think that a phase coupler would work on the subpanel. The signal would jump phases at the subpanel unstead of having to go all the way out on line to the transformer. Have you eliminated noise on the line as a source of your probelm?

yes, i have two 110 leads coming off my main and going to the sub (i think it's a 30amp sub). i have Not installed the coupler yet, that's my question... will the coupler work from the main to the sub?
thx!

I was amazed when I switched from a passive to active coupler..all my problems went away!

The coupler will work from either location. Distance plays a part in how well a passive coupler works.If you only have problems coming off the subpanel I guess I would put it in the subpanel since it is closer to the source of the problem. It I'm seeing it correctly you will also be coupling your main panel also but with a further run for the X10 signal to travel.

Adding a transceiver to the garage will work, too. It also might be cheaper. I found that whenever a signal from one part of the house didn't reach another, I could just add another transciever in that general area.
